听力原文：W: I want to register for this mathematics course. M: I'm sorry. Registration is closed. W: Closed? The clerk told me I could come back and register anytime during the first week of the class. M: Well, that's not possible. The computer's official student account has already been sent to the state. And that's what our budget is based on. Who told you that anyway? W: A woman here when I tried to register three weeks ago. She said I just had to pay a late fee. M: She must be a temporary worker. She doesn't have much training. Why didn't you register then? W: She said I couldn't until I had my birth certificate. Here it is. M: Your birth certificate? W: Well, I'm a new part-time student, so she asked for the identification. I don't drive, so I don't have a driver's license. M: Hm. There's no reason to demand a birth certificate. We only need to establish residency. A phone bill with your name and address on would be fine. W: Really? Only proof of my address? M: Yes. I'm afraid she gave you the wrong information. Still, you have to wait and take your math class next semester. W: But that's not fair. M: Well, I sympathize with you, but frankly, I don't think there's anything anyone can do for you. You're trapped in the system. If you want to, you can talk to the director. She'll help if she can. W: Great! M: Don't get your hopes up! (23)
